metabolism myo-inositol monophosphatase catalyzes the dephosphorylation of myo-inositol 3-phosphate in the last step of myo-inositol biosynthesis. Expression of IMP genes is correlated with expression of the gene for myo-inositol polyphosphate 1-phosphatase, which is involved in the myo-inositol salvage pathway, suggesting a possible salvage pathway role in seed development. Moreover, the partial rescue of the impl2 phenotype by histidine application implies that IMPL2 is also involved in histidine biosynthesis during embryo development Arabidopsis thaliana
physiological function myo-inositol monophosphatase catalyzes the dephosphorylation of myo-inositol 3-phosphate in the last step of myo-inositol biosynthesis. Myo-inositol monophosphatase is also important in phosphate metabolism and is required for the biosynthesis of cell wall polysaccharides, phytic acid, and phosphatidylinositol Arabidopsis thaliana
